Vedclass · Answer

(B) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group.$1$. $2-$Hydroxypropane $(CH_3CH(OH)CH_3)$ contains the $CH_3CH(OH)-$ group,so it gives a positive iodoform test.$2$. Methyl acetate $(CH_3COOCH_3)$ contains the $CH_3CO-$ group,so it gives a positive iodoform test.$3$. Benzophenone $(C_6H_5COC_6H_5)$ does not contain a $CH_3CO-$ group attached to a hydrogen or another carbon,so it does not give the iodoform test.$4$. Acetamide $(CH_3CONH_2)$ contains the $CH_3CO-$ group,so it gives a positive iodoform test.Therefore,Benzophenone does not give a yellow precipitate with iodine and alkali.

Which of the following does not give a yellow precipitate with iodine and alkali?
